tools/kvm_stat: fix handling of invalid paths in debugfs provider
When filtering by guest, kvm_stat displays garbage when the guest is
destroyed - see sample output below.
We add code to remove the invalid paths from the providers, so at least
no more garbage is displayed.
Here's a sample output to illustrate:
